# Description
<!-- What is the current behavior and what is the expected behavior? -->
<!-- If the issue is visual/graphical, please attach screenshots of the problem. -->
<!-- Add the issue details below this line and before the "Steps to reproduce" heading. -->
When a selection is made, the graphic items of both global and hierarchical labels do not get highlighted.
In the screenshot below it is obvious, but with small selections this is sometimes a bit confusing.

On a sidenote:
I had not used KiCad for a while, and at the moment I experience quite a lot of small (but distracting) issues. I am a bit in doubt on what the smallest issue is that is still worth reporting...
